A night course at the local community college is how I learned to run AutoCad.
I'd been drawing on a drafting table with a pencil for a long time, so I picked it up pretty fast.
I've got Auto Cad 12 and 2006, and Auto Sketch 9 which is what I use mostly.
The technology moves too fast to keep up with the new releases (for me anyway).
I suppose that if you were making drawings 100% of the time, you could do it.
I found a program that I was comfortable with, that would do what I needed, and I stuck with it.
Eventually you get familiar with the program, and can actually make working drawings without pulling your hair out.:smile:
Once you get the hang of it, you begin to see what a great tool it really is.
And that's what it is, just a Tool.
Just my opinion

Edit to add:
Be sure to get a book on the program that you finally select.
It will give you the commands and directions to all the little secrets and features the program has.
